IMPROVEMENT 1N BRAlniNe-MAc-HIN'ES. I

The Schedule rolex-red to in these Letters Patent and making of thesnme.

.To whom it may concern l iu Machines for Making Braid; and do herebydeciare the following to be a full and correct description thereof,reference being had to the accompanying drawing making part of this'specification, and to the letters and numbers of reference marked there-J on, similar letters and numbers being used in all the figures todenote the same parts.

The fabric produced by the braiding-machine with these improvements issubstantially a union oi' two or more braids, of the'same or diiie'rentcolors or maf terials, vjoined, together by interlocking their edgesvwhile in the process of making, and is accomplished mainly by makingthe run or groove that guides the spoolcarriers oi' a peculiar form, andby the construction and position of the driving-wheels and the horns onthem, whereby the force .that drives the carriers is applied in theproper direction.

Description of the Drawing.

Figure l is a view of the top plate, showing the shape of the run; also,by dotted lines, the position of the drivers and the horns on them. 1

Figure 2 is a top view of the gearing.

Figure 3 shows a longitudinal section, taken vertically through thecenters of the gear-wheels a b c d g;

Figure 4 shows the position oi' the strands of the braid as they areinterlocked.

General Description. .A is the top plate, having the run'S, as it iscalled,

. a vrooveof nearly uniform width, cut through it.

The parts of the plate inclosed by the run are called quoits,and theyare held in their places by being screwed to the tops of the studs o o,which are fastened to the lower plate B by passing through it, andhaving nuts screwed on their ends.'

These studs al hold -the driving-wheels a b c. d g,

l which 'are free to turn on the studs, and are furnished with teeth to-gear together and drive 'one another.

- a e'e" d" 9" are projections on the upper sides of the idriving-wheels, called horns.;

These horns are made of dierent heights;l those on the wheels a and gare high enough' to pass over the horns on the wheels b'and d nextj tothem, that they may not hit'in passing each otherkand drive the'carriers from one part of the run to another. These horns are'm'adc'in; pairs, so as to form recesses between ythem toy receive thestuds or lower ends of ,e. The oarners are indicated by the ljf3.456,7-8in iig, 1. -Thedrivingfwheels being put in motion in thedirection lindicated by the. arrows, each carrier in the end circles ofthe run will be driven around thatjcircleJby its lower end, whichprojects downbetween the horns on the wheel under that circle. (See g.-3.)

When a carrier, after passing around the endj'circle, .v comes to thecrossing in the run, the width :of that part of the carrier in the run'keeps it in such afposi-A tion that it enters the next circle or oval ofthe run, y

the horns on the next drivingwheel taking it from. the first one anddriving it forward. ff

Now, the run between the two outside circlesis composed o f two circlesor ovals, overlapping:each` other in the middle; this brings thecrossingsof the ,A

ovale in such a position that a carrier, having'entered the oval, cannotleave it at the middle crossing to en;

ter the next oval, but mustcontinue in the same'iintil it. gets back tothe outside circle it started from, Asu

that two carriers starting, one from eaehof. the'outside circles,l at ths ame time, will'pass around each. A other in the middle. (see 4 and 5in iig. 1,) wherethe' 'ovals overlap each other, and thisinterlockstheirthreads; and, as each carrierin the outer circle' in itstur'n passes around anotheriu the middle, it 'follows that the twobraids are interloched by each strand in its turn. (See iig. 4.)'

When the spool-carriers le'avethecuter circle of the -run theyenter thehorns e and e -on wheels b and'd, -whichdrive them forward until theycome to the crossing ofthe run where the ovals overlapeach other. Herethey arel taken by the horns e" e" ou the center wheel c, which drivetheui around the ends of the ovals, the lower ends of the carrierspassing inside of the hornsv e and c, betweleu them and the centers ofthe wheels on which they are, (see fig. 3,) .until they come to theother crossing, where they are again taken between the horns c' and s'on the wheels b and d, and carried to the outer circles -from which.they started. This keeps each set of strands by itself, :excepting atthe edges where they are interlooked, and it will be Aseen that anynumber of sets like the outer circles beorementioned may be joined inthe same .way by having the overlapping circlesor ovals placed betweenthem, as above described, and thus fonn abraid of'- strips of ilii'erentcolors or materials, either dat o r "circular, as may be desired. ,Thedotted lines gto the right hand of rig. 1 show how this extending of theovals can he made. l

The biaidis drawn up with fcedrolls placed above l. K the spools, in themanner usual in this class of maehines, and not necessary to be"particularly described here, nor have we deemed it. essential todescribe more patticularly the upper partof the spool-carriers, withtheir-tensions, Src., as any of the lusual modes;
